6/90 x/60
Then you will cross multiply and divide to get the answer which is 4
You can multiply each fraction on both top and bottom so that they have 24 as the denominator. The equation becomes
![\frac{20}{24} m- \frac{10}{24} = \frac{21}{24} m+ \frac{16}{24}](https://tex.z-dn.net/?f=%20%5Cfrac%7B20%7D%7B24%7D%20m-%20%5Cfrac%7B10%7D%7B24%7D%20%3D%20%5Cfrac%7B21%7D%7B24%7D%20m%2B%20%5Cfrac%7B16%7D%7B24%7D%20)
subtract 16/24 to both sides and you get
![\frac{20}{24} m- \frac{26}{24} = \frac{21}{24} m](https://tex.z-dn.net/?f=%20%5Cfrac%7B20%7D%7B24%7D%20m-%20%5Cfrac%7B26%7D%7B24%7D%20%3D%20%5Cfrac%7B21%7D%7B24%7D%20m%20)
now subtract 20/24 from both sides and
![\frac{-26}{24} = \frac{21}{24} m](https://tex.z-dn.net/?f=%20%5Cfrac%7B-26%7D%7B24%7D%20%3D%20%5Cfrac%7B21%7D%7B24%7D%20m)
<u />
multiply 24 on both sides
-26=21m
and divide by 21 on both sides
m=-26/21 or -1.24
Answer:
17.85 grams of vitamin C.
Step-by-step explanation:
0.6 x 7 = 4.2
0.35 x 5 = 1.75
4.2 + 1.75 = 5.95
5.95 x 3 = 17.85
Answer/Step-by-step explanation:
a. % of people who smoke = no. of people who smoke ÷ total no. of people surveyed × 100
Total no. of people who smoke is given = 4 + 36 = 40
Total people surveyed = 200
% of people who smoke = ![\frac{40}{200}*100 = \frac{40}{2}*1 = 20 percent](https://tex.z-dn.net/?f=%20%5Cfrac%7B40%7D%7B200%7D%2A100%20%3D%20%5Cfrac%7B40%7D%7B2%7D%2A1%20%3D%2020%20percent%20)
a. % of people who do not exercise regularly = no. of people who do not exercise regularly ÷ total no. of people surveyed × 100
Total no. of people who do not exercise regularly = 36 + 134 = 170
Total people surveyed = 200
% of people who smoke = ![\frac{170}{200}*100 = \frac{170}{2}*1 = 85percent](https://tex.z-dn.net/?f=%20%5Cfrac%7B170%7D%7B200%7D%2A100%20%3D%20%5Cfrac%7B170%7D%7B2%7D%2A1%20%3D%2085percent%20)
Answer:
The original goal is $25019.154 .
Step by step Explanation:
Let us assume that the origianl goal be x .
As given
Another project on Kickstarter for an iPad stylus raised 1,253% of their goal, raising a total of $313,490 .
1253% is written in the decimal form .
![= \frac{1253}{100}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1253%7D%7B100%7D)
= 12.53
Than the equation becomes
12.53 × x = 313490
12.53x = 313490
![x = \frac{313490}{12.53}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B313490%7D%7B12.53%7D)
x = $ 25019.154
Therefore the original goal is $25019.154 .
